Chronic care handoffs in otolaryngology: Pediatric to Adult Care Providers.

Objective: The transfer of care from pediatric to adult otolaryngology remains unexplored. Our study investigated practice patterns among pediatric otolaryngologists.

Methods: Twenty-question survey administered to otolaryngologists at the Society for Ear Nose and Throat Advancement in Children (SENTAC) and American Society of Pediatric Otolaryngology (ASPO) in December 2020 and July 2021 respectively.

Laryngocardiac Reflex: A Case Report and Review of the Literature.

Introduction: The vagus nerve has sensory and motor function in the larynx, as well as parasympathetic function in the thorax and abdomen. Stimulation of the superior laryngeal nerve can cause reflexive bradycardia.

Case: We describe a case of a 45-year-old man with pre-syncopal symptoms while exercising, and bradycardia found during cardiology workup.

Photodocumentation of the development of type I posterior glottic stenosis after intubation injury.

Bilateral vocal fold immobility may result from bilateral recurrent laryngeal nerve paralysis or physiologic insults to the airway such as glottic scars. The progression of mucosal injury to granulation tissue, and then posterior glottis stenosis, is an accepted theory but has not been photodocumented. This paper presents serial images from common postintubation injury to less common posterior glottic stenosis with interarytenoid synechia.

Neuromuscular induced phonation in a human ex vivo perfused larynx preparation.

Considering differences in laryngeal anatomy, degree of control, and range of voice qualities between animals and humans, investigations of the neuromuscular process of voice control are better conducted using a living human larynx in which parametric stimulation of individual laryngeal muscles is possible. Due to difficulties in access and monitoring of laryngeal muscle activities, such investigations are impossible in living human subject experiments. This study reports the recent success in developing an ex vivo perfused human larynx model, which allows parametric muscle stimulation and observation of its influence on phonation of a virtually living human larynx in a well-controlled laboratory environment.
